trolled mechanism which is shown as embodied in a service-providingdevice of the kind employed for automatically efiectingthe sale ofarticles and which are commonly known as vending machines. The presentinvention may be considered in generalas a variant form of ormodification of that invention by which it is adapted for rendering anentirely different form of service available. The coin controlledmechanism of the present invention asherei'nf disclosed is in control ofa timedservice-supplying device,

for inaugurating the service to be supplied thereby and then, after apredetermined "period of time has elapsed, for discontinuing suchservice, so that therebythe service rendered available is provided onlyover a predetermined limited period of time. While theservice-supplyingdevice shownherein as controlled by the presentinvention supplies electric current and while the embodiment of theinvention disclosed herein is particularly adapted to be employed inconnection with such device, it is to be understood as within the scopeof the present inventionthatit may be employed, should occasion arise,in connection with and for controlling the operation of other forms ofservice supplying devices in which a substantially similar'mannerofoperation is required. I j, y

In carrying out this invention some of the features disclosed andclaimed in my above noted prior application haK- G, been. retained insubstantially similar'for-m, while other features havebeen changed andfurther features have been incorporated, so that, on the whole, asubstantial departure has been made from this prior invention. It shouldbe noted that the, construction of the coin carrier and its immediateadjuncts is substantially the same as in my copendin-g a plication forpatent for vending machines, erialNo, 39,4l l2, filed 'June 1925, whichbecamalatent No.

In my application I 1,723,948, August -6,- 1929,011 which the magnetfeature is claimed in my copending divisional application Serial No.133,615, filed September'd, 1926, which became Patent No. 1,657,836,vJanuary 31,1928.

. One object of the present invention is to provide a coin controlledmechanism which is particularly adapted for controlling the operation ofa service-supplying device in such manner as first to initiate orinaugurate the available serviceand then, after a desired predeterminedinterval of time has elapsed, to discontinue the service thus provided,until another similar coin controlled operation.

is efiected, In this connection, another ob-' I ject of the inventionis-to provide a coin controlled mechanismi which is I particularlyadapted for heavy duty. Other objects are to provide a construction ofthis kind which is simple, strong, durable, effective, and inexpensiveto manufacture Other objects and advantages of the invention willhereinafter appear. 4

The invention includes various featuresof construction andCOIHbJIlfllBlOIlS' of parts,

which are set forth inthe appended claims,

and as will appear from the following de scription of one embodiment ofthe invention, which is illustrated in the accompanying drawings, inwhich: r

F ig. 5 is a diagram of electric circuits,

and v "Fig. 6 is a reduced front elevation of the tem le; apparatus inwhich the. invention is embodied, with some of the interior parts shownin broken lines.

A vertically disposed main frame plate 1 of thecoin controlled mechanismis provided, on both the front and rear thereof, with various flanges,projections and bosses, as shown in Figs. 1 and 2, to provide supportsand bearings for various operating parts of the coin controlledmechanism, as will hereinafter appear. A front frame plate 2 is disposedin parallel spaced relation to the lower portion of the main frame plate1 and is firmly secured to forwardly projecting portions of the latterby means of screws 3 (Figs. 1 and 6). The main frame piece 1 is ofsubstantially rectangular outline. andfits into a rectangular casing box4 adjacent the top and left side thereof,where it is secured in place byscrews 5 entering lugs 6 provided in the casing 4. A terminal block 7,of insulating material, is similarly secured in the upper right handcorner of the casing box t'by means of screws 8 and easing lugs 9.

A front vertically arranged baffle plate 10, curved inwardly at itslower end substantially flush with the lower end of the main plate 1, issecured to the adjacent right hand wall of'thecasing box 4 and serves todirect coins from the coin controlled mechanism into a money pan or coinbox 11 which is loosely received in and substantially fills thebottonrpart of-the casings: below the main frame 1 (Figs. 1 and 2'). Thecasing box 4 is closed by a'fr'ont door 12 hinged to the top thereof at13 and providedat the 'bottom with a suitable lock 11 (F igs. 2 and 6).The. door 12 is .cut out around'the major central portion of the frontframe'plate2, which projects to the outside through the opening thusprovided (Figs. 2 and 6-). The casing 1 may be conveniently mounted with9 its back against the wall of a room and secured thereto in anysuitable way.

A pair of line conductors or lead-in wires 15 and 16 may proceed froma'commercial supply service or from any suitable source of electriccurrent,.in Fig. 5 the line conductor 16 being shown as grounded merelyfor clarity of illustration. Three conductive terminal strips,comprising a short terminal strip 17 and a pair of longerterminal strips18 and 19, are mounted on, the insulating terminal block 7 The linewires 15 and 16 are connected respectively to the short terminal strip17 and to the right hand longer terminal strip 19 by means of bindingscrews 20 and 21. The devices for utilizing the electric current areconnected across the two longer terminal strips 18 and 19.

In thedrawings, the invention is shown as utilized commercially to"provide for. the

use of an electric hair curler 22. A pair of output or lead wires 23 and24am connected to the curler 22. and twisted together to form anordinary two-wire cord. One

of these leads 23 is connected to the lower terminal strip 18 by meansof a binding screw 25 and the other lead 24 is connected to the otherlonger terminal strip 19 by means of a binding screw 26. Also, tofurnish a light when needed in using the curler 22, a lamp 27 isprovided, having leads 28 and 29 connected respectively to the twolonger terminal strips 18 and 19 by means of binding screws 30 and 31.Obviously, instead of the hair curler 22 and the electric lamp 27, or inaddition thereto if desired, electric current may be similarly suppliedto any kind of electrically operated device, such, for example, as asuitable stove, an electric fan, or a radioreceiving set, merely byconnecting' their. respective .lead wires across the two longer terminalstrips 18 and 19.

For completing the circuit through the hair curler 22 and the lamp 27 toinaugurate the available service, and then, after a predeterminedinterval of time has'elapsed, for breaking the circuit to discontinuethe service, an electrical connection is made between the short terminalstrip 17 and the lower longer terminal strip 18, and this connection issubsequently broken. .Both of these results are accomplished by means ofa suitable circuit making and circuit breaking switch which isoperatedand controlled by the coin controlled mechanism. For thispurpose, service completing conductors, shown as wires 32 and 33, areconnected respectively to the terminal strips 17 and 18 by means ofbinding screws 34 and 35. The circuit wires 32 and 33 are connectedrespectively to switch terminals shown as binding screws" 36 and 37(Figs..1 and .2) mounted upon the top of aswitchbox or casing 38 whichcontains the switch mechanism. A journal pin 39 in the lower part of theswitch box provides a pivot for a service-controlling or switchoperating lever 40 which projects below the switch box (Figs. 1, 2 and5).

Any suitable form of switch may be em-' ployed and it maybe of astandardcommercial type. In practice a readily purchasable well' knowncommercial type of single pole, toggle, snap switch having a singlemetal operating lever has proved satisfactory and that 'is the switchshown 7 in outside elevation in Figs. 1' and 2. In

View of the well known construction of.

switches of this type, it seems unnecessary to illustrate its internalconstruction. However, for a clear understanding of the manner ofoperation, a simple but operable conventional form of a' circuit makingand breaking switch is shown diagrammatically in Fig. 5. As there shown,a contact member 41;,is connected by a con'ductor 42 with the bindingscrew 36 and a rocking switch arm 43 carried by the. rocking operatinglever 10 has a pig-tail connection 44 to the other binding screw 37. Inthe position of insulating plate 4L5.

the switch operating lever shown in the drawings i-gs. 1 and the circuitis open and will be closed by the rocking of this lever 40 to itsoppositely inclined position.

The switeh box38 is-supported on the front face of the outer portion ofthe main frame plate 1 with-the service-controllingoperating lever 40projecting downward. The backof the switch boX 38 rests against aninterposed The switch box 38 has a lower cover plate 46 which projectsbeyond its ends. A pairof L-shaped b-racketsorclips 47 are rivetedorotherwise secured to. the projecting ends of the cover'plate' 46 and ares e'- cured, by means or" a pair of screws48, to the frame plate 1. r g1 1 This electric switch and-more particularly its operating lever 4:0,forms a part of the coin controlled mechanismyduring the operation ofwhich this service-controllinglever 40 is operated in the mannerrequired so as to be rocked to its current supplying position, and thensubsequently, after the desired period of time has elapsed, to bereturned to its normal position shown in the drawings, in which thesupply of current is cut off. More broadly considered, however, therocking service-controlling lever 40 .by which therequiredoperatingmovement is'transmitted to the current controllingparts of the switch, conceivably might be utilized for operating someother form or service-supplying f device, which might not be electric,but where a substantial- 1y similar manner of operation would beeiiective, should occasion arise for utilizing the present invention inconnection with some such different service-supplying diavice, althoughthe coin controlled mechanism of the present invention is "particularlyadapted and intended for controlling a supply ofelectr'ic c'urrent,so asto render it available only over a predetermined limited period-of time.The features of construction provided in accordance with .the inventionfor thusoperat'ingthe service-controlling member, shown as the rockingswitch-operating lever 40-, will now be described. 7

Suit-a'bly spaced rearwardly from the main frame plate 1, a rocking gearsegment 49, which has substantially theform of an upwardly extendingarm, is looselypivoted upon a rocking operating shaft 50which extendsforwardly through the main frame platel and is journaled in a bearing 51tor-med thereon, and which extends rearwardly and its rear end isiournaled' in a bearing block secured to the back wall of the casingThis rocking arm 49 is normally disconnected from its operating shaft50, and thereby formsan initial operating member for oper ating therocking service controllinglever or switch operating lever' i0 whicht-lru sforms a second operating member, for operating the abovedescribed electrical service-supplying device. For this purpose, thegear segment arm 49 near its endlcarries a pair of laterally spacedoperating lugs or studs 53 and 54 which project forwardly throughanarcuate slot .55 in the mainframe plate 1. These studs .53 54 togetherwith the ends of the slot 55 may serve as stop means for limiting themaximum extent of rocking movement of the gear segment 49, which is moreparticularly desirable in its return movement, as will presently moreclearly appear. A pair of opposed operating screws 56 and 57 arerespectively screwed transversely through the forward ends oif 'therespectivestuds 53 and 54 for transverse adjustment relatively thereto.

When the gear segment 49 is rocked forward and back the opposedspacedends of these operating screws 56 and .57 will engage alternatelywith the opposite sides of the rocking service-controlling lever 40 andthus I these screws, together with the studs 53 and 1 54 by which theyare carried, form an adj ust able lost motionopera-ting connectionbetween the gear segment 49 and the service-controlling'switch operatingleverdO for rocking the latter, first to'its forward position and for rthen returning it to its normal positionshown in the drawings. Theoperating armor gear segmental? thus forms an initial opera-ting memberrelatively to which the service-controllinglever 40 is a secondoperating memnli'sm.

It will be noted that as the gear segment arm -49 moves forwardly theservice-controlling operating leverlG will not be rocked in her whichdirectly operates the switch 'mecha-- its for-ward direction until thegear segment 49 approachest'he end oi its forward movement and takes upthe lost motion provided between the end of the operating screw 56 andthe operatinglever 40. Similarly, as the gear segment 49 is returnedfrom its forward to its normal position shown in the drawings, the lostmotion then present between the ends of the other operating screw 57 andthe operating lever 40 will prevent the latter from beingreturned to itsnormal circuitopening position until the gear segment 49 approaches theend of its return movement. By suitably adjusting the operating screws56 and 57, the extent ofthe lost motion between them as to eachdirection of their movement may be varied, for thereby rocking thecircuit controlling switch lever 40 to the proper extent and at theproper point, in both the forward and. back rocking movement of the gearsegnentt9: In a usual snap switch construction, as above'noted, when themovement of the. switch lever ,40 has been substantially initiated inone direction, it will be snapped over toitsopposite position by theswitchmechanism, for thus quickly making or breakingthe electriccircuit, which is desira ble, as is well understood.

The coin controlled means for manually rocking the initial operatingmember or gear segment arm 49 to its forward position, for therebyclosing the electric circuit, will be described presently. ,An energystoring device is provided to be stored with energy by the gear segment49 during its forward movement and then to become immediately effectivefor returning the gear segment to its normal position. Also aspeed-retarding timing I so device is provided in connection with theenergy storing device for retarding the return movement of the gearsegment arm 49 over a predetermined interval of time, during which thesupply of electric current is provided. The energy storing device andthe timing device shown will now be described.

In the construction shown, a relatively small auxiliary frame isprovided for the energy storing device and for the timing device whichis shown as associated therewith. This frame has a front plate 58 and arear plate 59 which are tied together by spacers 60, shown as three innumber. This frame is supported at the rear of the upper portion of thevmain frame plate 1, and also at the rear of the upper end portion ofthe gear segment 49, by means ofthree small strips or clips 61, securedat the front face of the front plate 58 on the forward ends of thespacers 60 and having their projecting other ends secured, such as bymeans of screws 62, to rearwardly projecting portions or lugs formedonthe back of the main frame plate 1. V

- A main shaft 63, which forms both a spring-winding and a timing orretarding shaft, is journaled in the frame plates58'and 59 and projectsforwardly, where at its forward end it is journaled in a bearing64 onthe main frame plate 1 (Fig. 2). ,A springwinding pinion 65 is fixed onthis shaft 63 and engages with the gear teeth of the operating arm orgear segment 49. A convolute ribbon spring 66, of the usual clock type,surrounds the shaft, 63, with its inner end connected thereto and withits outer end anchored to the spacer 60 at the top of the frame (Figs.1, 2 and 3). The convolutions of the spring are arranged so that it willbe wound up by the counter-clockwise rotation of the pinion 65, asviewed from the front (Figs. 1 and 3), this'being the direction offorward rotation of this pinion as imparted thereto by the forwardrocking movement of the gear segment 49. \Vhen this spring has been thuswound, it acts through the pinion 65 asa return spring for the gearsegment 49,

and becomes immediately eifective'for this purpose under the controlofthe speed-re tarding timing device, which will now be described.

An automatically actingone-way clutching connection is provided betweenthe rotatable spring-winding and timing shaft 63 and the timing device,by which the timing device remains idle or inactive during the forward67 is loosely mounted on the shaft 63 at the rear of the'spring 66 andforms a rotatable part of the timing or retarding device. Just at theback of this gear a clutch disc 68, shown as having a single clutchtooth, is fixed upon this shaft, with its clutch tooth directedbackwardly in reference to the direction of forward rotation of theshaft. A one-way clutch pawl 69 is pivoted; by a pin 70, on the back ofthe gear 67, to be engaged by the tooth of the clutch disc 68 upon thereverse rotation of the shaft 63, while providing for the free forwardrotation of the latter (Figs. 2 and 4). It will be noted of Fig. 4 thatthe gear wheel 67, which is located forwardly of the section line onFig. 2, is accordingly shown in broken lines in Fig. 4. The clutch pawl69 is urged towards the clutch disc 68 by a small leaf spring 71attached to the gear wheel 67 (Figs. 2 and 4).

When the gear 67 is rotated by the shaft 63, through the flexing of thewound spring 66, this gear 67 transmits its rotation through a train ofspeed-multiplying, and correspondingly power-reducing, gearing shown ascomprising consecutively, a pinion 72 fixed on a shaft 73," agear 7 4fixed on this shaft and engaging a pinion 75 fixed on a shaft 76, a gear77 fixed on this latter shaft and engaging a pinion 78 fixed on a shaft79, and a gear 80 fixed onthe latter shaftand engaging a pinion 81fixedona final shaft 82 The opposite ends of the. three shafts 73, 76and 79 are journaledrespectively in the front and rear frameplates 58and 59. The final shaft 82 is j ournaled at its front end in the frontframe plate 58 and is also journaled in the rear frame plate 59 beyondwhich it projects. A ferrule 83 is fixed upon the rear projecting end ofthe shaft 82 and fixed upon this ferrule is a-fan or paddle 84. i

In accordance with well known principles, the air will offer asubstantial resistance to the rapid rotation of this paddle fan,whereby, through the above described connections, the return to normalposition of the switch operating arm or gear segment 49'will be retardedand delayed, so that the service-controlling operating lever 40 will notbe returned thereby to its circuit breaking position until apredetermined limited period of time has elapsed.

insteadthereof, some other form of retarding device might be connectedto the shaft 82, or

to a corresponding shaft orother rotatable part. For example, anescapement device substantially similar to those commonly employed inclockspsuitably constructed and adjusted to effect a proper timing,might be utilized for this. purpose. In fact, any suitable formofretarding or timing'device'may be employed inconnection with theinitial operating member or arm i9. A g

The clock type of spring. 66} shown has proved of particular utility asan. energy storing. device, in that it economizes space, is of lightweight, and atthe same time provides for the storing of an effectiveamount of energy therein. However itissto be understood as within theprovince of the invention to employ some diiferentkind of suitableenergystoring device For example. a weight. might I beused for this purpose;Likewise, a. differ ent form: of springmightbeused andloperativelyconnected in a different manner to the initiaLoperat-ing. member or arm-49.

v In. carrying out'the: invention, a counter or odometer is prov-ided'for indicating the number of operations of" the apparatus, and

* which consequently correspondingly indicates the number of coins whichhave been deposited in themoney pan 11. The indication of. the countermay be seen through a suitable window providedin the top of thecasingil', this window comprising a slot in the casing covered at thei'nsidebya transparent plate 85, such as glass, heldin place a slottedshell86 securedby rivets 2') to the casing f. The counter per se may beofa usual construction, as shown, and tl'ierefbre need not be describedin detail. It issup ported in paitdirectly byt'he, main frame plate 1".at the top and. left side'tliereof and in part by aibracket plate87secured'by screws 88 I) to a projecting portion of the mainframe'pl'atei 1. The counter shown comprises three axially alignednumber wheels 89 loosely mounted on a number wheel shaft 90, and apairof transfer pinions 91 loosely mounted on a pinion shaft 92. I v

The units wheel of the counter, which is the one at the r'ear andappearing at the right'in Fig. 2, is actuatedby avdriv'e pinion 93'loosely mounted on the pinion shaft 92 and havingconn'ected thereto adrive gear 94i The drive gearj94 is engaged and driven by a pinion- 95which is formed'on or carried by large intermediate gear 96, bothjjournaled" ona stud 97'. Ehis intermediate gear 96' is engaged anddriven by the gear 87' to which the timing device is connected, 7 asabove described. The above noted gearing, connecting'this gear wheel 67-with the? unit's wheel of the'number wheels89 is so proportioned thateaclitime the gear-wheel 67 is rotated the units number wheel will'bemoved forward to the extent ofa' unit indication. This occurs, throughthe clutch connection 68" and 69., each. time that. the gear segment oroperating arm. 4.91s returned from itsforward to itsfnormal position bythe spring 66; 'Ihus each service-supplying operation of the apparatuswill be indicated by the number wheels 89 of the counter. The; normallyineffective manually operable device coniprising the parts of thecoincontrolled. mechanism which are made effective by neansof a proper coin,for'movin-g the initial operating member or gear segment arm 49- to itsforward position, thereby: to inaugurate the'service supplied by theapparatus willv now be described, together with the various associatedcooperating parts.

It will. be noted that the forward portion of the rocking operatingshaft 50', which is journaled. in the bearing. 51 is of larger diameterthan the: rear portion of this shaft upon which the combined operating.arm and spring-winding gear segment a9 is loosely mounted. Between theinner end of the bearing 51 and the front face of the gear segment 4:95this shaft 50 is; shown as flattened on its opposite sides (Figs 1 andleverarmf98 is mounted on th-isfiattened portion of the shaft 50 to=.berocked thereby and. normally extends towards the left at a slightinclination, as viewed. from the front (Fig. For obtaining adequatestrength, with inexpensiveness of manufacture, this lever armis shown asmade up 'offou-r plate parts secured togetherby rivets. (Figs. .2 and 3This lever arm 98 forms a normally ineffective freely idly-movabledriving member for the gear; segment armfrom which it is normallydisconnected. A normally ineffective one-way coupling deviceto be madeeffective by a moving coin is providedv for coupling or connectingthelever arm 98'to V the gear segmentarm lll so t'liat this gear segmentwill then he driven bythe lever arm 98in the forward direction only ofthe rocking; movement ofthe latter. The particular coupling device shownasprovided for this purpose will now bejdescribed.

Above thero'cking operating shaft- 50 and parallel'theretoastar wheelshaft '99-is j'ournaled' in and projects through'ahearing 100 formed onthemain frame plate 1 coindriven; star wheel 10.1 is fixed upon thefront end of this shaft for rotating the latter. Theteethof'thisst'arwheethaveabrupt faces in the counter-clockwise directioninwhich it is to be rotated, the othersides or' faces of these teeth beinginclined. One of the teeth of this star whee1,.at the lower par-ti ofits periphery ,5 is always normally positioned tobe engaged by the upperedge-portion of a moving coin'for thereby imparting a step of rotativemovementtothe star wheeli second or rear star wheel 102, similar tothefirst or front star wheel 101 and having the same number and kind ofteeth correpondingl'y directedlis fixed upon the rear end of the shaft99, and is shown (Figs. :1 and 3) as having its teeth positionedfmidwaybe tweenthose of the front star wheel 101. This rear star wheel102 is atvthe front of and adjacent to the upstanding gear segment arm.49.

' Both of the star wheels 101 and 102 are yieldably positioned andnormally thus maintained by means of a yieldable stop device. For thispurpose, in the construction shown, a stop roller 103 engages betweenthe teeth of thefront or coin-driven star wheel 101, at the rightthereof, as viewed from the front in Fig. 1. This roller is rotatable ona headed stud 104 which projects forwardly from the upper end of anupper arm of a bell-crank lever 105 the other arm of which projectstowards the right, this lever being pivoted on a headed stud 106 whichprojects from the front of the main frame plate 1. The lower end of acoiled retractile spring 107 is'connected to the outer end of thelateral arm of this lever and the upper end of this spring is anchoredto'the main frame plate 1 by means of a stud 108. This spring 107 urgesthe stop roller 103 towards the star wheel 101 and as this star wheel isrotated the inclined cam faces of its teeth will push back the stoproller 103 against the tension of the spring 107 which will react toposition the star wheel and will be effective to impart the finalportion of a step of movement there. to. Rotative movement of the firststar wheel 101 imparts a like movement to the rear star wheel 102, whichalso is correspondingly positioned by the yieldable stop roller 103. Anormally ineffective coupling member is 'inade effective by one of theteeth of the rotating rear star wheel 102 to form a one-way drivingconnection of the driving lever 98,

,in the forward movement of the latter, with the gear segment arm 49,thereby to impart forward rocking movement 'to the latter throughout thefull extent of its operating movement, thereby to wind the spring 66 andto rock the service-controlling lever or switch operating'lever40 to theservice-supplying or circuit closing position, whereby the service willbe inaugurated in the manner hereinbefore described.

In the construction shown this coupling member comprises a two-armedsubstantially arcuate normally transversely extending pawl 109, shown asmade up of two similar axially spaced parts which are rigidly connectedtogether by two pins 110 and 111, of

which the pin 110 is at the right end, or end of the tail arm, of thepawl and the pin 111 is at an intermediate position in the en gaging armof the pawl, which projects towards the left. Between these pins thecoupling pawl 109 is pivoted on the gear segment arm 49 in notchesprovided in the top of a forwardly projecting lug or ear 112, on a pivotpin 113 which passes through this lug and through the body of the arm 49(Figs. 2 and3). r

The engaging end of the driving arm of this pawl 109 is normallymaintained above and out of the path of the end of the driving lever 98in the rocking movement of the latter, by meansof a coiled retractilespring 114 which at its upper end is connected, between the two parts ofthis pawl 109, to the tail arm pin 110 and at its lower end is anchoredto a pin or stud 115 which projects from the front of the gear segmentarm 49. This spring 114 normally holds the driving arm of the couplingpawl 109 against a stop lug or stud 115 which projects from the front ofthe gear segment arm 49. The pin 111 which connects the two parts of thedriving arm of the coupling pawl 109 is provided between these parts ofthe pawl with a roller 116 which, in the normalposition of the gearsegment arm 49 and of the star wheels 101 and 102, is positioned just atthe right of the inclined-face of'the end portion of the lowermost toothof the rear star wheel 102 and substantially in contact therewith (Figs.1 and 3.). t

As this star wheel 102 moves a step forward it will depress the drivingarm of the coupling pawl 109 to bring its engaging end into the path ofthe end of the driving lever 98in the forward movement of the latter andwillthus hold this pawl at its gear segment engaging position during thetime that the" and is continuing to move while this star wheel is movingand depressing the engaging end of the coupling pawl 109, as willpresently clearly appear, some free space or lost motion is providedbetween the endof the driving lever98 and the engaging end of thecoupling pawl 109 in the normal position of this driving lever and gearsegment arm 49, as clearly appears in Fig. 3. At the time when this lostmotion is taken up, the engaging end of the coupling pawl 109 will beheld down by the end of the tooth of the star wheel 102 which isthen inengagement with the pawl roller 116.

Soon after the end of the driving lever 98 magma Z driving lever 98isnotched as shown (Fig 3.) to provide thereon an undercut'driving face117 at an acute angle to the radius of this lever and the engaging endof. the coupling pawl 109 is correspondingly pointed'at an acute anglecomplementary to this driving face. As the gear segment'arm 49 is rockedforwardly by the driving'lever 98, through the intermediary of theengaged coupling pawl 109, the gear segment arm carries with itthecoupling pawl and moves thela-tter bodily away from the rear'starwheel 102.

At this time-the moving coin, together with the spring-pressed stoproller 1-03,'willhave repositioned the star wheels101 and 102'.

The construction of the coupling pawl 109 to operate inthe manner justdescribed forms one of the features provided for, assuring that theapparatus shall be in a nonoperable condition until thegear segment arm4.9 has returned to its normal position tocomplete a service-supplyingoperation which has been inaugurated, as will hereinafter clearlyappear; j

The manually, operable means provided in carrying out the invention forrocking the driving lever 98" in the forward direction and forconcomitantly moving the coin to impart a step of'rotative movementtothe star wheels 1'01 and 102 will now be described together with theancillary features controlling the operation of the coin controlledmechanism and thus of the service-supplying operation.

Near the top of its exposedcentral portion the front frame plate 2 hasthrough it a slight ly inclined coin slot 118. A normally ineffectivefreely idly movable rocking coin carrier 119 is fixed-upon the forwardend of the operating shaft 50, so that thereby the driving lever 98 andthe coin carrier 119 are positively and rigidly connected" together forconcomitant unitary rocking movement. At

its front the coin' carrier 119 is provided witha pivot stud 120 (Figs.1, 2 and 6') whic h is journaled in the front plate 2 in axial alignmentwith the operating shaft'50'. The coin carrier 119 extends above andbelow its pivotal axis and is of substantlally arcuat'e segmental shapetowards the leftfas viewed from the front in Fig. 1.

The arcuate periphery of the coin carrier 119 at the left of its axisisprovided with a limiting lug 121 which may move between lower and upperstop lugs 122 and 123 provided on the main frame plate 1' for limitingthe rocking movement of the coin carrier 119 and of the driving lever98. At its top the coin carrie'r119 is provided with a coin holdin gslot- 12 l and outwardly from this slot it carries a coin'movingfinger125 to engage with substantially the center of the left side of a coin126 ('(Fig. 1) the lower edge of which is seated in the slot 124.. Thisfinger 125 wtll pass through the hole of a vaslier and cause it to bediscarded. The C0111 holding slot 124 is normally in alignment withthe'lower portion of the coinv slot 118 in the front plate 2' with theend of the finger 125 just at the left of'the latter slot. The righthand inclined face of the upper stop lug 123 is substantially inalignment with and just clear of the upper part of thercoin slot 118'andservesas a guide and support for the inserted coin 126.. i y

A laterally curved horseshoe magnet 127 is pivoted at 128 in a notchprovided in thetop of the lower stop lug 122, where it is held in placeby a screw pin1 29. The upper spaced pole ends of the magnets armsextend at an upward inclination towards the-right above 9 and beyond theupper stop lug 123 and normally slightly overlap the upper portion of ithe coin slot 118. The magnet arms-are yieldingly pressed against thestop lug 12, which is notched to receive them (Figs. 1 and 2) by aspri-ng130 which is carried by the magnet by means of a pair of lowerandupper pins 131 and 132 witli: the u per end of this spring engagingagainst a lug 133 provided on the frame plate 1.

When a proper coin is pushed through the coin'slot 118 its upper edgewill engage the forward'mhgnet arm to lift the ends of the magnet andhasthe coin passes inwardly it will be received at its upper edgebetweenthe spring-pressed magnet arms which will position= the coin sothat its forward edge will be" clear ofthe coin slot 118- in the-frontplate 2 when the coin is moved away from this slot by the rocking of thecoin carrier 119, so that 3100 gage and release the rollers 134 and1 35thereby causing a paramagnetic slug to be-discarded by the coin carrier119 coacting with the magnet'127.

A transversely extending coiled retract-ile return'spring 137 for thedriving lever 98 and the coin carrier 119 is anchored atone end to theend of a pin 138 secured in a forwardly projecting portion of the mainframe plate 1 atthe'lower right hand corner thereof. The other end ofthe spring 137 is connectedto the lower end 'of'the coin carrier 119'through the intermediary of a bent or curved lever 139 located for themost part in a deep slot 140 in the right hand and lower portion of thecoin carrier and pivoted to the lower end of the coin carrier by a pin141. The return spring 137 is connected to thelever 139 below its pivotpin 141;, so that thereby the upper sides thereof, by means of a pin142, a pair of reversible pawls 143, one of which appears in Fig. 1.These pawls are, urged towards their intermediary position (Fig. 1) by acorresponding pair of small coiled'retractile springs 144 connectedtotails of the pawls and anchored to the pivot pin 141 of the feeler lever139. An arcuate saw-tooth ratchet 145, shown as secured to the front ofthe main frame plate 1, is provided for the'pawls 143.

When the coin carrier 119 is rocked substantially to its full extent thepawls 143, in both the forward and the return movements of the coincarrier, will wipe over the ratchet 145 and escape from thecorresponding end thereof. In an idle movement of the coin carrier, whenthere is no coin in its slot 124, the pawls 143 may reverse on theratchet 145 to permit the return of the driving lever 98 and the coincarrier 119 to their normal position, the upper end of the feeler lever139 then passing across the empty coin holding slot 124 as these pawlsreverse. A coin in the slot 124 will prevent the reversal of the pawls143 on the ratchet 145, thereby compelling a full forward movement ofthe driving lever 98 and the coin carrier 119 before they can bereturned to their normal position. This prevents the loss of coins inthe apparatus.

In this connection, however, it should be noted that after the coincarrier 119 has begun its return movement the pawls 143during theirreturn movement on the ratchet 145, will be locked against reversal, sothat thereby the coin carrier 119 cannot be again moved forward from apartially returned position, but is compelled to complete its returnmovement for the escape of these pawls from the lower end of the ratchet145. This locking against forward movement of the coin carrier 119results by reason of the locking toggle formed by the pawls 143 with thelower arm of the lever 139 between the pawl pivot 142 and the pivot 141for the lever 139'on the coin carrier 119.

This locking of the coin carrier 119, by the pawls 143, against forwardmovement from a partially returned or intermediate position willlikewise similarly lock the driving lever 98 against forward movement.This locking of the driving lever 98 has particular utility in thecarrying out of the invention as one of the features in the meansprovided to prevent a second, orsuccessive, service-supplying operationfrom being inaugurated before the first has been completed, as willpresently clearly appear. It might be furthernotedin this connectionthat when the operating arm or gear segment 49 is coupled to the drivinglever 98, as above described, the extent of forward movement imparted tothis operating arm 49 by the driving lever 98 will be determined by theupper stop lug l23-for the coin carrier 119. o

In view of the fact that the freely movable driving lever 98 and coincarrier 119, after having been rocked to their forward service providingposition following the insertion of a coin, willbe immediately startedon their return movement by the coin carrier spring 137, while theoperating arm or gear segment 49 will be returned slowly to its normalposition while the service is provided, it will be realized that unlesssome preventive means were provided, the driving lever 98 could be againrocked forward, either from a partially returned or from its fullyreturned position, a successive number of times, thereby again to rockforward the operating arm 49 from a partially returned position thereofand thus prolong the service rendered indefinitely without the insertionof any more than a single coin.

Obviously also it is desirable, as a vsafeguard to the customer after acoin has been inserted,-that assurance of a complete service-supplyingoperation of the apparatus shall be provided. For this purpose, meansare provided to prevent the apparatus from being restored to an operablecondition until the gear segment arm 49, in its retarded movement, hasfully returned to its normal position for discontinuing the servicewhich has been paid for. Accordingly, in carrying out the invention,means are provided to prevent the return of the coin carrier 119 to itsnormal coin-receiving position until the gear segment 49 hasv completedits retarded return movement to its normal position.

In the construction shown, 'a three-armed stop pawl 146 for the drivingarm 98 in its return movement is pivoted on a headed stud 147 whichprojects from a rear thickened portion of the main frame plate 1 (Figs.1, 2 and 3). This stop pawl has an upstanding engaging arm, a tail armprojecting to the right and a releasing arm projecting to the left, asseen from the front in Figs. 1 and 3. This pawl is urged to rock irraclockwise direction, as viewed from the front (Figs. 1 and 3), by acoiled retractile spring 148 connected at its upper end to the end ofthe tail arm of the pawl and at its lower end anchored, by means of ascrew 149, to a rearwardly projecting portion of the main frame plate 1.This pawl148 is stopped in its spring-actuated movement by the abut tingof its tail arm againsta stop lug 150 which projects from the back ofthe frame plate 1.

.tained by the operating screw 151 in the normal position of the gearsegment arm 49 (Figs. 1 and 3), The driving lever 98, together with thecoin carrier 119,-thus may be rocked idly forward aindbackthroughout'the extent of'their movaaeneerto a less extent, without thedriving lever 98having any engagement either with thecoupling pawl 109orthe stop pawl 146. p

When the gear segment arm 49 is moved forward by the driving lever 98,following the insertion of a coin, it-will lift the operating screw 15 1away from the releasing'arm of the pawl 1'46 and the pawl spring '148will then beeoine eifecti ve'to move the stop end of this pawl intothetterminal portion of the return path of the driving lever 98. WVhenthe driving lever 98 and the gear segment arm 49 have completed theirforward movement, the coin carrier spring 137 becomes immediatelyetteetive for quickly returning the driving lever 98 and the coincarrier tow ards their normal position, while the gear segment arm 49 isreturning slowly. To wards the endof such return movement of the drivinglever 98 the lower side ofits outer end will abut/against the stop endof the pawl 146, therebyarresting the return movement and preventing thefull return of the coin-carrier 119 to its normal'coin 1 8-"- ceivingposition, whereby the coin controlled mechanism will be 1n anon-operable condition. During the terminal-part of the re tarded returnmovement of the gear segment arm 49, after the desired fpredete'rminedinterval of timehas elapsed, the operating'screw 151 will come intoengagementfwiththere leasing armofthepawl 146 and as the gear segment'arn '49 completes its return movement it will rock the pawl 146 back toits normal position, out. of engagement with the driving lever 98,whereupon the coin carrier spring "137 will complete the'returnmovementof'th-e driving lever-98 and coincarrier 119, so that the latter wlll'bereturned to its normal coin-receiving position and the coincontrolledmec'hanism will thusloe inan operable condition for asubsequent operation of. the entireappara'tus. It will be noted of theparticula'r construction shown and as'already described'th'at'thecooperating relation existing betweenthe stop pawl l46"and thecoincarrier pawls 143 is without the insertion of a'coin.

effective to lock thedrivinglever 98 against forward movement while itis in engagement with the stoppawl 146, by reason of the fact that thecoincarrier pawls 143 cannot then reverse on -the ratchet 145 to'permitsuch forward movement. This prevents the gear segment arm 49 from beingrockedforward from some intermediate position of its retarded returnmovement, and thus prolongthe service indefinitely following theinsertion of a single coin.

It will also be noted ofthe particular construction shown that as soonas the 'driving lever 98begins its rapid return movement it will releasethe coupling pawl 109 which then will be immediately. snapped by itsspring'114to its uncoupling ordisengaging position at a timewhen thegear segment arm 49 is'a-tits forward position and isonly beginning itsretarded return "movement. The coupling pawl "109 will thus be at anineifective position throughout the return inovement of the'gear segmentarm- 49, sothat forward movement of the driving lever 98 could bepermitted and would then be ineffective to drive the gear segment, asthedriving lever 98 could rock idly beneath the inefiective couplingpawl 109 at time during'the retarded return movement of the gearksegment arm 49, as well as after-it has returned to its normal position.Thusthis-coupling pawl construction in itself wouldbe'eife'ctivetoprevent the prolongation ofthe service It therefore becomes evidentthat, in the particular embodiment of the invention shown, either oneorgthe other of these fea tures for preventing undue prolongation of theservice beyond thetime paid fOrmight be retained and theother omitted.Consequently, the particular construction shown has the advantage thatitprovides latitude for suitable modification in construction, whichmight bedesirable in some instances, For example, a slight modificationof the feeler lever 139 in relation to its pawls 143 would permit thedriving lever 98 and coin carrier 119to be moved forward from anintermediate position of their return niovement, in which case theparticular pawl'eonstructionshown would prevent the driving forward ofthegear'segment arm 49, Also it is'conceivable'that some entirelydifferent device other than the feeler lever 139 and its pawls 143 mightbe employed for preventing the loss of coins in the apparatus. Also theconstruction of the coupling pawl 109 may be changed in such manner thatthis pawl would then retain its eiiective or engagingposition'throug'hout the majer portion of the return movement ofthe'gea'r seg-f ment arm 49, and would then be moved to its ineffectiveposition as the gear segment arm approaches the termination of itsreturn movement to normal position. In such case, the locked pawls 143would be effective to prevent forward movement of the driving lever 98.Also in case the stop pawl 146 should be omitted and, for example, somedifierent device employed for rendering the coin controlled mechanisminoperable, then the particular coupling pawl construction shown wouldpermit the idle and inefiective rocking of the driving lever 98 to aforward position during the retarded return movement ofthe gear segmentarm 49.

While the coupling pawl construction shown is particularly intended anddesigned to be employed in a coin controlled mechanism for aservice-supplying device, such as shown, in which the service providedis extended over a period of time, it is to be noted that thisconstruction of coupling pawl is also suitable to be employed in adifferent construction of the coin controlled mechanism for a differentpurpose, such, for example, as that disclosed in my above notedapplication for patent Serial No. 224,051 filed October 5, 1927, whichis there shown as employed to operate a vending machine. This otherapplication discloses the above noted different form of the couplingpawl,

.which as above noted, might be employed in carrying out the presentinvention.

'At the completion of the forward movement of the coin carrier 119 whenit carries a coin 126, as shown in Fig. 1, the coin may drop upon aninclined ledge 153 provided on the forward face of the main frame plate1, from which it will slide and drop upon the lower inwardly turned endportion of the baffle plate 10 and thence into the money pan 11. A coindisengaging or kick-off pawl 15% is provided to assure the disengagementof of the coin from the coin carrier. This pawl is privoted at the frontof a thickened portion of the frame plate 1 on a pin 155 and nor mallyrests on the top of the magnet spring lug 133, against which it ispressed by a bent wire spring 156. This pawl extends over the coincarrier 119 and has its free end inclined downwardly, to be lifted bythe advancing coin and upon the return movement of the coin carrier toengage and dislodge the coin.

The manually operable means shown as provided in carrying out theinvention for imparting forward rocking movement to the driving lever 98and the coin carrier 119 against the tension of their return spring 137will now be described. Within a large slotted opening in the coincarrier 119 there is provided on the coin carrier an internally toothedarcuate rack 157. A shaft 158 passes through this opening and is journaled at its ends in the frame plates 1 and 2. A pinion 159 fixed onthe shaft 158 engages the coin carrier rack 157 and at its forward endhas connected thereto a spur gear 160 at the front of the coin carrier119. The gear 160 is engaged by a similar gear 161 which is rotatable ona headed journal stud 162 projecting inwardly from the front plate .2.These gears 160 and 161 are contained in a recess formed in the innerface of the front frame plate 2, as shown in Fig. 2. In view of the factthat en by a tubular pinion 163. The rear end of this pinion 163 issmooth and is journaled in a bearing 164 formed on the front of the mainframe plate 1, through which the end of this pinion extends. The forwardend of this pinion has thereon a head 165 which is journaled in thefront frame plate 2 in a bearing 166 forming a front boss on this frameplate; A handle knob 167 has its hub 168 journaled in the outer end ofthe bearing boss 166 and is fixed upon the outer end of a handle shaft169 which extends inwardly loosely through the pinion 163 and projectssome distance beyond the rear end thereof. A clutch element 17 0,journaled within the bearing boss 166, is connected to the hub 168 ofthe handle knob 167 to be positively rotated in either direction by thelatter. The pinion head 165 forms a cooperating clutch element with thishandle-driven clutch element 170. These clutch elements 165 and 170 areshown (Fig. 2) as provided with complementary inclined interengagingclutch teeth so as to form a oneway driving clutch of the ratchet type.

The inwardly projection portion of the handle shaft 169 carries a coiledcompression spring 171 which acts between the handle shaft 169 and theinner end of the handle pinion 163 for maintaining a positively actingone-way driving connection between the clutch elements 165 and 170. Theforward end of this clutch spring 171 bears against a washer 172 whichbears against the inner end of the pinion 163. The inner end of thisclutch spring bears against a nut 173 screwed on the inner end of thehandle shaft 169 and by which the tension of this spring may beadjusted. The inclined clutch teeth of the clutch elements 165 and 170are shown (Fig. 2) as disposed or directed so that clockwise rotation ofthe handle knob 167 (Fig. 6) will positively drive the pinion 163, whilerotation of the handle knob 167 in the opposite direction will cause thehandle-connected clutch element 17 0 to yield and rotate on the pinionclutch element 165, thereby apprising the customer that the handle knob167 is being rotated in the wrong direction.

When the handle knob 167 is rotated in the forward or clockwisedirection, the driving lever 98 and the coin carrier 119 will be positively rocked in the forward direction against the tension of theirspring 137, through the intermediary of the above described drivingconnections comprising the clutch elements 165 and 17 0 and thepower-multiplying toothed gearing, beginning with the pinion 163 andending with the coin carrier 157. \Vhen the coin carrier 119 carries acoin the operating arm or gear segment 49 will then also correspondinglybe rocked to its forward position, to inaugurate the service by which,in the construction shown, a'supply 0- electric current becomesavailable, and at the same time during this forward movement of the gearsegment 49 to wind the spring 66, which after the predetermined periodof time, under the control of the speed-retarding timing device, asabove described, will discontinue the service which has been provided.

lVhile the gear segment arm 49 is being thus rocked forward the handleknob 167 may, if desired, be released at any time to obtain a fresh gripthereon, or it may be rotated alternately forward and back withoutreleasing the grip of the hand thereon, in either case the engaged coincarrier pawls 143 then preventing reverse or return movement of the gearsegment arm 49, driving lever 98 and coin carrier 119 from theirpartially advanced position, thus maintaining them and permitting theirforward movement only, as has been already described.

The operation of the coin controlled mechanism shown has been alreadyfor the most part described, and will now be summarized. When the coincarrier 119 carries no coin, it

= and the driving lever 98 may be freely idly rocked to their forwardposition or to any intermediate position and then will be idly returnedto normal position by the coin carrier spring 137. In the constructionshown, the limited forward movement of the driving lever 98 and the coincarrier 119 will be completed with about one complete rotation of thehandle knob 167. \Vhen the coin carrier 119 carries a coin, as shown inFig. 1, the forward rocking movement of the coin carrier 119 will atfirst idly move the coin 126 beyond or out of alignment with the coinslot 118in the front plate 2, and at this time the pawls 143 will becomeengaged with the ratchet 14 5 to prevent return movement of the coincarrier 119, driving lever 98 and operating arm 49.

As the coin carrier advances, the coin will immediately engage theadjacent lower tooth of the coin-driven front star wheel 101, which itnow rotates, together with the rear star wheel 102. As the coin thusmoves it lifts and passes beyond the end of the kick-ofi pawl 154. Therotating rear star wheel 102 immediately depresses the engaging end ofthe coupling pawl 109 against the tension of its spring 114. WVhile thecoupling pawl 109 is maintained in this position by the rotating rearstar wheel 102, the forwardly rocking driving lever 98, having taken upthe intervening lost motion, is brought into'engagement with the end ofthe coupling pawl 109, and thus drives the gear segment arm 49 in itsforward rocking movement. While the star wheels 101 and 102 are beingdriven forward by the moving coin, the coupling pawl 109, in its engagedcondition, is carried bodily away from the rear star wheel 102 as thegear segment arm 49 is rocked forwardly by the driving lever 98. In theinitial portion of its forward movement the gear segment arm 49 releasesthe stop pawl 146.

As the gear segment 49 is driven forward by the driving lever 98 itrotates the pinion 65, thereby, through the pinion shaft 63, to wind thespring 66. In the construction showmjust following the completion of arotation of the shaft- 63, it carries the clutch tooth of the retardingclutch disc 68 beyond the end of the spring-pressed pawl 69 of'the gearwheel 67, preparatory to engagement with this pawl for operating thetiming device having the air paddle 84 and the counter having the numberwheels 89. As the forwardly driven gear segment arm 49 approaches thetermination of its forward movement, its left hand operating screw 53comes into engagement with the service controlling operating lever 40and rocks the latter to close the electric switch, which is shownconventionally in Fig. 5 as the switch arm 43 and contact member 41. Thecustomer will be apprised of the comple-' tion of this part of theoperation by the coin carrier 119 reaching the limit of its forwardmovement, whereby the engaged driv-y ing clutch elements 165 and 170will stop the further forward rotation of the handle knob 167. Thepower-multiplying gearing driving connecton makes the winding of thespring 66 easy. I

When the handle knob 167 is released at the completion of its forwarddriving movement, the coin carrier spring 137 immediately re turns thedriving lever 98 and the coin carrier 119 to the point where the drivinglever 98 abuts against the stop pawl 146. Immediately upon the beginningof this return movement of the driving lever 98 it releases the icoupling pawl 109, whereupon this pawl is immediately snapped to itsdisengaging position by its'spring 114. The gear segment 49, now havingbeen set free, is slowly rocked backwardly'and is finally returned toits normal position by the reversely rotating pinion 65, which is nowdriven by the unwinding of the spring 66, through the shaft 63. As thisshaft 63 is thus rotated reversely it carries with it the gear 67 byreason of the engagement of the tooth of the clutch disc 68 with itspawl 69, whereby the air paddle 84 opposes, the spring 66 and delays thereturn of the gear segment 49 to its final normal position over thedesired predetermined period of time, which. in the particularconstruction shown willbe in the neighborhood of ten minutes. Duringthis period of time While the gear segment arm 49 is returning, electriccurrent will be supplied for heating the hair curler 22 and for lightingthe electric lamp 27.

As the gear segment arm 49 approaches the limit of its retarded returnmovementits right hand operating screw 57 will come into engagement withthe service-controlling operating lever 40 and will rock this lever inthe opposite direction, which will operate the switehto openthe'eleetrie circuit. Also as the gear segment arm 49 approaches thelimit of its return movement, its pawl-operating screw 151 will comeinto engagement with the stop pawl 146 and release the latter from itsengagement with the driving lever 98, whereupon the coin carrier spring137 will immediately snap the coin carrier 119 back to itsnormalcoin-receiving position relatively to the coin slot 118 in thefront plate 2. This,

together with the extinguishing of the lamp 27,Will apprise the customerthat the current has been cut off and that the apparatus is now incondition for a seubsequent operation by the insertion of another coin.The completion of the operation will be indicated by the number wheels89, through the gear connection by which they are driven from the gear67 as the latter is rotated by the spring 66. The illustrated embodimentof the inven- .tion has operated successfully and satisfactorily in use.It is obvious, however, that various modifications may be made in theconstruction shown in the drawings and above particularly described,within the principle and scope of the invention as defined in theappended claims.
